assalam o alaikum,
I have super power 78CC SP-70 bike. 2010 model. problem are:
1- Handle is vibrating on speed 40 and above. right hand grip feels more vibration. due to vibration my hand is not active and difficult to control accelerator ( as riding in winter your hand freezes)
2- how to adjust carburator for maximum mileage. when slowing down accelerator from 4th gear silencer shouts like misfire. ( silencer is not original super power. it is a modified one)
3- spark plug is little brown in center while blackish on outer circle.
4- battery ( when charge from dc-adaptor outside ) is charging , when in bike not charging. I have removed battery from bike, checked voltage on wires coming from charger it shows 12v dc approx and also bulb is lighting when connected to them
please suggest the solutions
thanks
